But it doesn’t sound like Hayden. It doesn’t sound like /anyone/ in the cast.
That fact that we’re having this discussion, about which /actor/ we each think that voice belongs to (given that it could be attributed to Qui-Gon but it’s not Liam’s voice) rather than anyone knowing for sure, shows that it’s not good.
I always thought that it was Cliegg Lars saying NOOO! He has the same husky voice.
